How It Works

Five Simple Steps

Set the temperature you want, then let the cup turn green when the drink matches it. A proposed sensor in the handle could also read heart rate when you hold the cup.

  1. 1

    Fill Smart Thermo Thermos

    Fill Smart Thermo Thermos with your drink.

  2. 2

    Set the Temperature Gauge

    Choose the drink temperature you want. Green means the drink matches your setting.

  3. 3

    The Sensor Measures

    The temperature sensor measures the liquid. Holding the handle could also let a proposed heart-rate sensor take a reading.

  4. 4

    The Controller Compares

    The smart controller compares the drink to the temperature you set on the gauge.

  5. 5

    Know Before You Sip

    The cup turns green when the drink is at your set temperature, so you can understand it before taking a sip.

Interactive Demo

Try Smart Thermo Thermos

Choose a drink condition. Green means the drink matches the temperature you set on the gauge.

Green

Just Right

Your drink matches the temperature you set on the gauge. That is what makes the cup turn green.

The Problem

Have You Ever Taken a Sip Without Knowing?

Drinks can look the same whether they are too hot, too cold, or just right. Smart Thermo Thermos was invented to make that information easier to see.

Too Hot

A drink that is unexpectedly hot can be uncomfortable and may cause burns.

Too Cold

Sometimes you want your drink at a particular temperature without constantly checking it.

Hard to Tell

You usually cannot determine a drink's exact temperature just by looking at it.

Smart Thermo Thermos was designed to make this information easier to understand at a glance.

The Solution

One Cup. One Look. Instant Information.

Smart Thermo Thermos combines a reusable cup with sensors, a settable temperature gauge, and a color-changing exterior. A person would set the drink temperature they want. A temperature sensor would measure the liquid. A small controller would compare that reading to the gauge setting and tell the cup which color to display. Green means the drink is at the temperature you chose.

Set the temperature you want on the gauge. Green means the drink matches that setting. Blue is colder, red is hotter, and yellow is a proposed future check.

Too ColdJust RightCheck DrinkToo Hot

Blue

Too Cold

The drink is colder than the temperature you set on the gauge.

Green

Just Right

The drink matches the temperature you set on the gauge. That is what makes the cup turn green.

Yellow

Check Your Drink

A proposed future sensor system could warn the user when the drink needs additional attention.

This is a proposed future sensor idea, not a claim that Smart Thermo Thermos can detect contamination today.

Red

Too Hot

The drink is hotter than the temperature you set on the gauge.

Why Smart Thermo Thermos?

A Helpful Idea for Everyday Drinks

Smart Thermo Thermos is useful because it turns hidden information into a color anyone can understand.

Easy to Understand

Colors provide information without needing to read a screen.

Reusable

Designed as an alternative to disposable drink cups.

Technology + Everyday Life

Shows how sensors and electronics can improve everyday objects.

Designed With Safety in Mind

The concept could help users recognize when a drink is hotter or colder than the temperature they set on the gauge.

Who Could Use It?

Made for Everyday People

Smart Thermo Thermos is a concept for many kinds of users. It is not a medical device and does not claim medical benefits.

Students

A colorful way to check a drink between classes.

Parents

A visual reminder before handing a drink to someone else.

Teachers

A classroom example of sensors in everyday design.

Travelers

Helpful when a drink has been sitting in a cup holder.

Athletes

A quick look at whether a drink still matches the temperature they set. A proposed handle sensor could also try to read heart rate when they hold the cup — not as a medical device.

Office Workers

Useful at a desk when a mug or cup has been sitting too long.

The Science Behind the Idea

Sensors, a Settable Gauge, Color, and Charging

Smart Thermo Thermos uses ideas from electronics and design. These are possible technologies that could be used to build a working prototype.

Temperature Sensors

Electronic temperature sensors can measure temperature and send information to a controller. In this concept, a sensor would sit where it can read the liquid inside the cup.

Settable Temperature Gauge

A temperature gauge on the thermos could let a person set the drink temperature they want. The controller would compare the real drink temperature to that setting. When they match, the cup turns green. That is what “just right” means in this invention.

Microcontrollers

A small programmable controller could receive the temperature measurement, compare it to the gauge setting, and determine which color should appear.

SET preferred = temperature on the gauge
IF drink is hotter than preferred → RED
IF drink matches preferred → GREEN
IF drink is colder than preferred → BLUE

Handle Heart-Rate Sensor

A prototype could include a heart-rate sensor in the handle. When a person holds the cup, the sensor could try to read their heart rate through their hand. This is a possible technology idea, not a medical device, and it would not diagnose or treat any health condition.

Color-Changing Technology

A prototype could potentially use LEDs or thermochromic materials to create visible color changes. These are possible technologies, not a finished product.

MagSafe Charging

MagSafe charging uses magnets to snap a charger into the right spot. Then power can move into the battery wirelessly, without holding a cable in place. A Smart Thermo Thermos prototype could include MagSafe-style charging in the smart base. This is a possible technology that could be used to build the invention.
